Process behind this logic?

I am unable to understand how does this logic work? Like we pass certain arguments to a function then what happens? how does the system know if we have passed the arguments for the keys or the values?

  **Your code so far**

const createPerson = (name, age, gender) => {
// Only change code below this line
return {
// Only change code above this line

Challenge: Write Concise Object Literal Declarations Using Object Property Shorthand

Link to the challenge:

This createPerson function takes three arguments: name, age, and gender. I’m assuming name and gender are strings and age is a number. The system doesn’t know anything else about them other than that. You are creating and returning an object with the three properties name, age, and gender and assigning each of these properties their respective values passed into the function. You are telling the system what to do.

Remember, you can write the property/values using the traditional long form:

return {
    name: name,
    age: age,
    gender: gender

This challenge is asking you to convert that the shorthand form, but you are still doing the same thing.

The name of the variable is the key and the value the variable contains will be the value.

const name = 'John';
const age = 32;

const user = {
} // John
user.age // 32

Thanks, it gave me a bit clarity on the issue.
